setting the initial focus

[Raja S.]

How does one set the initial focus to a control such as a picture box?

Suppose I have a form with a single picture box on it.
When the application starts to run I would like to set the focus to the
picture box so that it can respond to KeyDown events.

I tried placing a picBox.focus in a Form_load event handler but that didn't
seem to help.

Any suggestions?

Thanks in advance,
Raja

Surely the picturebox doesn't have a KeyDown event?

Assign the control the lowest 'TabIndex' and it will be focused
automatically.

Set the picture box's Tab Index to 0.

See the documentation on the Focus method describing the preconditions that
must be met to set the focus.

Thanks for the response but picture boxes don't seem to have the
tabindex/tabstop properies appearing in the properties window.

In form_load if I try to set

picbox.tabstop = true
picbox.tabindex = 0

the focus still doesn't go to the picture box on start up.

I'm able to place a pixbox.focus in a MouseEnter event handler and then I
get the behavior I'd like. But I presume there ought to be a more direct
way of having a picture box the initial focus on application startup.

What am I missing?

Thanks,
Raja

Raja,

Webform or windowsform, they act very different in this?

AFAIS pictureboxes cannot get the focus.

The picturebox has no key events so why bother with the focus? If your
ultimate goal cannot be achieved why spend time on it?

Thanks for the follow-up. I have wondered why for a picture box there are
no keyevents in the event drop-down-combo-box. But interestingly VB.net
-does- allow me to write such an event handler:

Private Sub picBox_KeyDown(ByVal sender As System.Object, ByVal e As _
System.Windows.Forms.KeyEventArgs) Handles picBox.KeyDown
...
End Sub

As I mentioned in an earlier note, I am able to give the picture box focus
with:

Private Sub picBox_MouseEnter(ByVal sender As Object, ByVal e As _
System.EventArgs) Handles picBox.MouseEnter
picBox.Focus()
End Sub

and then it responds to KeyDown events. I'm wondering if there is a way for
it to get the initial focus automatically on startup.

Thanks,
Raja
